To all w hom t may concern Be it known that I., EDGAR G. CAsAD,a cit-y izen of theUnited States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Metal Separators, of which the following is a specification.

My invention is an improved ore separator by means of which heavy ores, such as flower gold and platinum may be separated mechanically from the dirt without the use of mercury or other chemicals.

Referring to the drawings forming a part of this specification:

Figure 1 is a side elevation of my ore separator.

Figure 2 is a plan view of my separator.

Figure 3 is a transverse vertical section of my separator on the line 3 3v of Figure 1 looking toward the right. i

VFigure 4 is a plan view of the upper separator tray. Y Y

Figure 5 is a fragmentary plan view of the lower separator tray.Y

Figure 6 is a sectional view of the lower tray.

In the drawings 1 indicates a frame comprising four standards 2 2 and 3 3, upper rails 4 secured to the upper ends of said standards, lower rails 5 secured to the lower part of said standards, uprights 6 connected to rails 4 and 5 midway between the standards 2 and 3, transverse rail 7 connectingthe upper rails 4 4 and transverse rails 8 connecting the rails 5 5.k The" rails 4 and 5 incline downwardly at a slight angle from the standards 3 to the standards 2. A hopper 9 is mounted on the high end of the rails 4 4 Vin which hopper is an inclined bottom 10 which inclines downwardly towards the said end of the frame, said bottom being provided with a transverse row of holes 11 near its lower edge.

Suspended on flexible straps 12 securedY to the upper rails 4 4 is a trough 13 which inclines downwardlyfrom under the hopper to the opposite end of the separator parallel to said upper rail. 1n the bottom of said trough is a tray 14, the bottom of which tray is formed with riffles 15 extending transversely of the tray. Above the tray 14 in the upper part of the trough 13 is mounted a tray 16 which is provided with perforations 17 in its high end under the hopper 9 and a short distance below said hopper,

On the rail 8 'at thehigh end of the frame 1 is mounted a motor 18. the shaft 19 of which extends longitudinally of the machine par-1"` allel to rails 5 and is journaled. in a bearing 2O on the rail 8 at the lower end of the machine. A shaft 21 is journaled parallel to the shaft 19 in bearings 22, 23 and 24 on one of thestandards 2,one of the uprights 6 and one of the standards @n the shafts 19 and 21 are pulleys 25 and V2G respectively over which travel a belt 27. On the shaft 21 near its respective ends are secured eccentrics 28 and 29 which turn within scotch yokes 30 L and 31 secured to the under Side vof the trough 13. Y

A pump 35 is mounted on oneof the cross rails 8 through which pump extends the shaft 19 on which is secured the pump piston.

An Yinlet pipe 36 connectsto the pump which pipe is placedin a stream or other source of water supply. A pipe 37 leads from the outlet of said .pump into the hopper 9 just the high end ofthe bottomlO.

The tray 14 consists of two side walls 40 40, an upper end wall 41` a bottom wall 42 extending from the end wall 41 a short distance and the riftles 15 which extend from the lower Vedge of said bottomV wall 42 to the lower end of the tray. AThe i'iffles comprise a plurality of metal trough-shapedriflle sections, each of which is bent downwardly upon itself at one edge forming flanges 43 which fit over the other edge of the adjacent section, said sections resting in the bottom of the tray 14 and secured at their ends to the side walls 40 40. The tray 14 is shorter than Vthe trougluits upper end wall 41 resting just above the first row of holes 17. A plate 44 is mounted in the upper end of the trough under the perforations 1T and above the tray 14`and extends downwardly over the upper end wall 41 of the tray 14.

Ure dirt is placed in the hopper 9 and water is pumped therein, by the pump 35 through pipe 37 The water washes the ore down the bottom 10 through the holes 11 into the high end of the tray 16 from which the rocks and so forth pass down and out the lower end of said tray and the ore dirt passes through holes 17 onto plate 44 and into the upper end of the tray 14 and over the riflles 15, where the ore settles inthe riiles 15 and the sand passes out of thelower end of the tray. W'hile the ore dirt passes through the machine the trough 13,-plate 44, andthe trays above y25, belt 27, pulley 26` frame, an inclined trough 14 and 16 are agitated by the motor 18' through the medium of the shaft 19, pulley shaft 2l, eccentrics 2S and 29 and scotch yokes'B aiid'll The' ore is readily recovered from the tray lei.

Having described my invention, 'I claim:

l. In an ore separator, aframe', an inclined trough mounted on said frame, a tray in the bottom of said trough and extending longitudinally thereof, the bottom of said tray being` corrugated, means whereby Vone side of said trough is reciprocated and the other Side thereof` isf gyratedfsad reciprocationl being substantially transversely'of said trough.

2. -nan" ore-v separator as described, a

"mounted on said fr'ar'ne, a tray inL the bottom of said trough, thelbottom of said tray being corrugated, a tray `iii-the upper part of said troughfprovided with perforations in its high end, and

.means for'gyrating` one'side of said trough While reciprocatingthe other side thereof.'l Y 3. In-*an v-ore separator as described, a frame, -an inclined trough mounted on said frame, a tray inthe bottom of said trough, the bottomof said vtray being* corrugatechand a tray in the upper partof saidrtrough providedfvitlr perforations'in its high end-` va hopper above the highend of said trough, the bot-tom Wall ofsaid lhopper inclining- -doivn- Wardly` toward the highf'end of said trough, the lower end of saidbottom wall being perforate'd. 't y 4 fIn an ore separator as described. a frame, flexible strapsv secured to saidv frame, any inclined ,trough suspended on said straps,

a tray in the bottom of said trough, the bot` tom of said trayT being corrugated, tray in the upper part of said trough provided with perforations in its high end, a shaft journziled on said frame, ececntrics on said shaft, and scotch yokes rigidly secured to said trough and adapted to be'operated by said eccentrics. i ln an ore separator es described, a frame, an inclined trough flexibly mounted en said frame, a hopper above the high end of said trough, a drive shaft journaled on said frame, a motor for driving 'said shaft, means o'iereted by said shaft for gyr'ating one side of said trough while reciprocating the other si de thereof.

6. Inv an ore separator, a frame, an inclined trough niountedon said frame', :i plate in the upper end of said trough, a tray with rii'iies in thebottom of said trough extending from the loiver end of the-trough to a point justundeithe lower edge'ofs'aid plate, and a tray in the troughabove said plate andsaid tray, saidflatter tray having perforations in its upper end over said plate and meansl for gyirating' one side of said trough Whilereciprocati'ng the other side thereof.

In an ore concentrator, a frame, a trough, flexible means connecting-the frame and theA trough, a shaft, eccentrics on the shaft and means connecting the-eccentrics and the trough Wherebyone 4siderof the trough is reciprocated in the arc ofa circle andthe other Side, is gyrated..

In testimony whereof Iaiix my signature.
